Conflicts with Antivirus Programs
This document is a machine-translated draft and is currently undergoing review. Some content may be inaccurate or differ from the original Korean version. For the most precise information, refer to the Korean documentation.
Symptoms
- Running the player installation file produces no response, or an error message appears during the installation process.
- After installation is complete, the screen goes black or playback stops when playing a video.
- An antivirus program identifies Kollus Player as a virus or threat and blocks it from running.
- The agent executable is repeatedly deleted, preventing Kollus Player from launching.
Cause
Kollus Player is a safe program that has passed global security standards. However, the real-time protection feature of some antivirus programs may mistakenly identify the player's security functions as a threat and block access to content.
Resolution
| Antivirus program | Action |
|---|---|
| Alyac | Right-click the system tray icon > Uncheck [Real-time Protection] |
| V3 Lite / V3 | Right-click the system tray icon > Uncheck [PC Real-time Scan] |
| Kaspersky | Right-click the system tray icon > Click [Pause Protection] |
| Avast | Right-click the system tray icon > [Avast shields control] > Disable for 10 minutes or until restart |
| McAfee | Right-click the system tray icon > [Change settings] > [Real-time Scanning] > [Turn Off] |
| Bitdefender | Open the program > Click [Modules] at the bottom > [Settings (gear icon) for Antivirus] > Uncheck all checkboxes under [Shield] |
| AVG | This program often aggressively blocks the player. If issues occur, temporarily uninstall the program, then install the player and verify playback. |
Other security scanning programs (app check, etc.)
If a real-time security scanning program such as App Check is running, it may mistake the player installation file for a corrupted file and block installation with a warning message. Temporarily pause the real-time detection feature of the program or close the program, then try the installation again.
